《数学课程标准》指出,让学生学习有价值的数学,让学生带着问题、带着自己的思想自己的思维进入数学课堂对于学生的数学学习有着重要的作用。就是要让学生上有准备的数学课,作为一名高年级的数学教师,笔者利用数学教学准备案,对如何进行小学数学的课前预习设计,做了初步探索与研究。承前启后,助学新知通过预习学生可以复习、掌握一些旧有的知识,初步认知知识的构架和网络,为完成由旧到新、由浅入深、由简单到复杂的知识迁移奠定基础。准备案就可以从旧知入手,开 The Mathematics Curriculum Standard points out that having students learn valuable math and having students enter the math class with their own thoughts and thoughts in their own right plays an important role in students’ math learning. Is to allow students to have a prepared math class, as a senior math teacher, the author of the use of mathematics teaching preparation, how to carry out primary school mathematics preview design, made a preliminary exploration and research. Throughout the past, alumni and new students can review and master some old knowledge and preliminary cognitive frameworks and networks through preparatory students so as to lay the foundation for the transition from old to new and from simple to complex and from simple to complex knowledge transfer. The record can be started from the old knowledge, open
